WINDOW CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 773,330, dated October 25', 1904. Application filed February l1, 1904. Serial No. 193,177. (No model.) I

To (t/Z whom, t may concern:

Beit known that I, EDMUND H. LUNKEN, a citizen of the United States, residing at Oincinnati, Ohio, have invented certain new and useful Improvements in Window Construction, ofv which the'following is a speciiication.

My invention relates to screen arrangements adapted more particularly to the window construction such as is disclosed in applications for Letters Patent of the United States filed by Bernard J. Hausfeld and Edmund H. Lunken September 14, 1903, Serial No. 173,118, and November 27, 1903, Serial No. 182,860, in whichis disclosed-a swinging frame carrying sashes and pivotally mounted in a main frame.

In the accompanying' drawings, Figure 1 is a vertical section of a window construction embodying my invention. Fig. 2 is a detail front view showing the manner of hinging the screen-frames to the swinging frame. Fig. 3 is a detail sectional view of a part of the swinging frame and the screen carried thereby with a catch for holding the screen in position. Fig. i is a vertical sectionalview taken through the hinge of Fig. 2.

In the drawings, 3 indicates the swinging frame, pivoted to swing vertically or horizontally in a main frame 2.. Within this swinging frame a center parting-strip is riveted at 4. Angle-iron strips 6 are removably secured to the frame 3, and between these angle-iron strips and the center parting-strip 5 the guideways for the sashes 7 and 8 are formed.

In order to associate with the swinging frame a pair oi' screens, I cut away the flange of the kangle-iron 6, which bears against the frame 3, the cut-away portion being located at the center of the window, and in the recess thus formed I arrange a plate 17, one on each side of the window. Each of these plates has a hole therein for the reception of a pivot-pin 18, which is held in place by a Cotter-pin 22, the pivot-pin 18 being headed on its inner end. These pins receive the hinged members 19 and 20, secured, respectively, to the upper and lower screens, and they complete the hinged connection between the said screens and the swinging frame. By this construction the f screens are hinged together at the center of the swinging frame, and they are held at the top and bottom by the spring-catches 21 or by any other suitable means. When itis desired to remove the screens, the Cotter-pins 22 are removed, and this allows the hinge-pins 18 to be Withdrawn, thus disconnecting the screens from the swinging frame and also fromeach other. When the screens are in place, it will be of course understood that the sashes can be cleaned on the inner side of the window without manipulating the screens in any way; but to wash the outside of the window the swinging frame is reversed in position. The upper screen then becomes the lower one, and by swinging the screens in toward the centerof the room the outer side of the sashes may be reached' for cleaning.

vWhen the screens are not in use, the plates or ears 17 may be withdrawn from the recesses in the angle-iron strips 6, and the'said recesses may then be filledv each by a plate 23 of such size as to present a flush face with the face of the angle-iron strip, thus making a neat appea-rance and presenting an advantage over the common arrangement which involves the use of guideways placed on the window-frame, which remain permanently in place during the winter or when the screens are not in use and which present an unsightly appearance. Of

course it will be understood that the angle-iron strips 6 on both the outer and the inner side y ot the swinging frame may be provided with the recesses and the removable plate, so that -in case it is desired to arrange a screen or blind either on the outer or inner side of .the frame this may be done.V

It will be understood that by associating the screens with a swinging frame they may be readily attached, removed, or repaired by simply swinging the frame onits pivots and bringing the screens to the inner side of the window, where all work or adjustment may be conveniently performed.

It will be understood that the frame 2 is suitably connected with the wall of the building and extends along all four sides of the window-opening, and the swinging frame 3 moves in the direction of the arrow X, Fig. 1, about the horizontally-disposed pivots-one IOO at each side of the swinging framewone of y which is indicated at a.. The ears 17 are held in the recesses in the guide-strips by screws, one of which is shown in Fig. l as holding the plates 23.

I. claim l. ln combination, a main frame, asecondary frame centrally pivoted thereon to be reversed in position, a swinging screen hinged to the secondary frame and a sash movable in the secondary frame and leaving an opening controlled by the screen, substantially as described.

2. In combination a main frame, a secondary frame centrally pivoted therein to be reversed in position, a pair of screens hinged to the secondary frame, and a pair ot' sashes movable in the secondary frame and leaving ope-nings controlled by the screen, substantially as described.

3. In combination a mainframe, a secondary Vframe centrally pivoted therein to be reversed in position, a swinging screen carried thereby and swinging about horizontally-disposed pivots, and a movable member carried by the secondary frame to close or open the space within said frame controlled by the screen, substantially as described.

4. In combination a main frame, a second* ary frame centrally pivoted therein to be reversed in position, a pair of screens hinged at the central portion of the frame to turn about horizontally-disposed pivots, and movable members carried by the secondary frame to close or open the space Within the said frame controlled by the screens, substantially as described.

5. In combination, a frame, guides for the sash having recesses, hinge-pieces or ears titted to the said recesses, and a screen or screens pivotally supported bythe said pieces, substantially as described.

6. In combination, a frame, guides of angle-iron secured thereto with recesses in their attached ianges, ears or hinge-pieces in the said recesses and secured to the frame, and a screen or screens pivoted in the said ears, substantially as described.

7. In combination in a Window construction, a frame, a strip secured thereto, having an ear or hinge-bearing, a pin held therein and a pair of screens pivoted on the said pin, substantially as described.

8. In combination in a vvifldoW construction, a `frame, a recessed strip, an ear fitted to thc recess, a screen pivoted in the ear, and a block or filling-piece for the said recess when the screen and ear are removed, substantially as described.

In testimony whereof I aix my signature in presence of tvvo witnesses.

EDMUND H. LUNKEN.
